Fastener Fair Stuttgart: Hall 4 Stand A10
Carlo Salvi SpA has recently launched onto the market the header model 616 WS – a 6-die progressive header capable of handling wire with diameter from 10mm to 17.5mm.
Wire is fed by grippers, which ensure very high precision (+/-0.05mm) thus avoiding damage to wire and offering the maximum clamping over a greater wire surface area. One set of grippers covers the whole standard wire diameter range for which the machine is rated and avoids the use of wire stops, reducing drastically set up times and operating costs.
The cutter holder is fully guided in order to avoid even minor flexing, while transfer fingers consist of independent finger units. The part to be transferred is pneumatically serrated by fingers so that the correct air pressure can be applied to each set of fingers as needed.
The oscillating transfer provides for greater flexibility and degrees of operation available for the opening and closing of the fingers; a special device allows retention of the part during ejection from dies and is ideal for the production of short, special and very complex shape parts.
K.O on the punch side is innovative and independent from ram movement; trimming is made with an advanced cam system that is permanently assembled on the header; and the independent hydraulic lock of the dies are further devices that make the 616 a complete machine.
The header model 616 WS can be equipped with a pre-heating system. The pre-heating system with induction, if housed in a strategic position, allows the operator to heat the material from 600°C up to 950°C and then it can be transferred in to the tooling area. Prior to the pre-cutting area there is an optical pyrometer that constantly monitors the correct wire temperature. This is linked to the transfer finger, in order to ensure only material with the correct temperature reaches the working area.
A special refrigeration system positioned in the die holder ensures circulation of the cooling fluid, while the fire-proof sound enclosure and automatic firefighting equipment assures maximum safety when working in extreme situations.
